Plot
The story serves as an alternate final chapter to Harry Potter and the Philosopher's Stone. Upon waking up, Hary Potter finds himself in front of Nicolas Flamel who explains that the Philosopher's Stone is merely a powerless decoy, and that he secret of his immortality is constant use of Polyjuice Potion to polyjuice himself back into his younger self.

According to Flamel, Albus Dumbledore only sent Harry down into the corrdior because he hoped that facing Lord Voldemort in these "controlled conditions" would be a way to prepare him for his future confrontation with the warlock. Finally, Flamel explains that he will impersonate Gilderoy Lockhart in the coming year to offer personal training to Harry under the guise of being the new Defense Against the Dark Arts teacher.
